Sep 2013 バリスティックレンジ試験委託
再突入カプセル形状の飛翔体を用いたバリスティックレンジ自由飛行試験を実施し、光学観測によって飛翔体挙動を記録する。東北大と機構のバリスティックレンジ試験結果を比較することで、設備間特性と遷音速不安定性を把握する。
Apr 2013 バドミントンシャトルコックの飛翔特性の解明と航空工学分野への応用
シャトルコックのダイナミクスを考慮した状態で飛翔の空力的研究を実施し、その成果による高速飛翔体の減速機構の新機軸を展開する
Jul 2011 揚力装置組込み翼の試作と風洞試験における空力データ取得
本課題の試験研究実施責任者らは、流体における境界層のはく離を防止する制御システムを開発し、特許登録を受けている。この技術を航空機の翼に応用すれば、高揚力装置組込み翼の開発が可能となるが、どの程度の効果があるかは実証されてはいなかった。
